Considering how popular the various high-profile music services have become on Android, it's a little strange that none of them have offered something like NextSong built in. It's strange, that is, until you remember how slow most of them are to conform to new Android functions like heads up notifications. In any case, music fans should definitely check out this handy app from independent developer Reactiv Sudios, whom we've featured before on Android Police.

Anybody who owns an ADT-1 has noticed the inexplicable absence of a Play Music app, something that became even more apparent after the Nexus Player began shipping with it. Well, the wait is finally over! An update to the Play Music app began rolling out earlier today, and it includes a banner on the Leanback Launcher for those of us with Google's development hardware. If you've got a Nexus Player, you haven't been left out with this update.

Sometimes you've just got to sit back and marvel at the ingenuity of some Android developers. While Motorola was busy putting expensive infrared sensors all over the front of the new Moto X to enable a few gesture controls, developer OnTheGo Platforms was adding it in with something that just about every smartphone already has. Behold, BrainWave, an app that lets you play, pause, and navigate your music like a frickin' Jedi.

Rdio's Android app got a teensy, tiny update today, adding gapless playback to all devices running Android 4.1. According to the "What's New" section of the Play Store page, the feature was added in by popular demand. For the uninitiated, gapless playback is exactly what it sounds like: a seamless transition from one track to the next. It's a big deal for some users, and much harder to do on a streaming music service than on local playback.

It seems that just about every major organization or service is being targeted for a gigantic data breach these days. Spotify was the latest service to be attacked, and yesterday the music streaming company specifically told Android users to upgrade their apps soon to protect themselves. The update is available today, but Spotify isn't taking any chances: it's created an entirely separate entry in the Play Store to make sure users get the point.

Most of the music services available today have some kind of radio feature, automatically generating playlists based on artists, genres, and other musical variables. But what about those of us who have vast hordes of pirated music from college sensible and legally-obtained MP3 collections? Pioneer is hoping to make an alternative DJ mix from your own local music files with the new MIXTRAX app.

Say you want a new playlist without having to meticulously add tracks and albums one by one.

Do we need another streaming music service? There's Pandora for people who always want to listen to something new, Spotify for people who want access to a large number of music as soon as it comes out, and All Access for Android users who want to combine streaming new music with the albums they've already backed up to Google Music. Then there's Rhapsody and Rdio for, I guess, the same people who like Spotify.

Remember when Microsoft angered legions of fans by announcing that the Xbox One would require an Internet connection to use? The company reversed that decision, but thus far, the Xbox Music Android app has functioned in much the same way. Fortunately for it, streaming music is already an established thing, so there won't be nearly as many people excited to find out that the newest version of the app now supports playing playlists offline.

Since its introduction, Google Glass has been in the unfortunate position of having relatively limited functionality. However, with a steady stream of updates and eventually the emergence of the Glassware tab in the MyGlass interface, we've known the elusive wearable was due for some more exciting things. A few weeks after announcing plans to add Play Music to Glass, Google has quietly added it to the list of apps supported on the elusive wearable.

One strength of iOS is that everything works seamlessly together. If you have iTunes installed on your computer, it doesn't take much effort to get music over to your iPhone. With Play Music, Google has taken a different approach for Android users looking at an out of the box experience, and if you don't have the internet connection to rely on the cloud for music listening, it's less than ideal. doubleTwist takes the iTunes approach, and with the reinvented doubleTwist Sync app that's now available for Windows, it looks more promising than ever.
